Circuit tracers or signal tracers are used to troubleshoot circuits. They are relatively simple electrical testing instruments that enable electricians and other users to locate, trace and identify common electrical problems such as breakers, shorts, and open circuits.

Clamp meters are ammeters that can measure current without the need to disconnect the wires where the measurement occurs. They provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends.

Ground fault circuit interrupter (GFCI) testers are used to check for improper wiring conditions in GFCI devices such as electrical receptacles. They detect leakage currents that are smaller than those used in fuses and circuit breakers, but still large enough to cause harmful electric shocks.

Megohmmeters generate high voltage, low current signals for testing the breakdown strength of electrical insulation. They are called megohmmeters because the insulating resistance of a properly designed product is expressed in mega ohms (M ).
